We look at the division of 90662876 by 621 
Let's see how many times 621 fits into 90662876.

On to step 1:
9 divided by 621 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 621

Going ahead to step 2:
When dividing 90 by 621, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Append the next digit (6) from the dividend to 90 and continue with: 906 / 621

Advancing to step 3:
906 divided by 621 is 1 with a remainder of 285.
The next digit of our result is 1. 
Result so far: 1.0
If we take 621 away from 906, we end up with 285.
Fetch the next digit (6) from the dividend, attach it to 285 and continue: 2856 / 621

Step 4:
621 can be fit into 2856 4 times, resulting in a remainder of 372.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 372 after subtracting 2484 from 2856.
Include the next digit (2) from the dividend after 372, then repeat: 3722 / 621

Going ahead to step 5:
When dividing 3722 by 621, we get 5 with a remainder of 617.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
The remainder is 617 after subtracting 3105 from 3722.
Grab the next digit (8) from the dividend, add it to 617, then carry on: 6178 / 621

Let's proceed to step 6:
621 can be fit into 6178 9 times, resulting in a remainder of 589.
Use 9 as the next digit of our solution. 
Result so far: 1459.0
Subtracting 5589 from 6178 leaves us with 589.
Fetch the next digit (7) from the dividend, attach it to 589 and continue: 5897 / 621

Advancing to step 7:
The number 621 fits into 5897 9 times, leaving a remainder of 308.
Use 9 as the next digit of our solution. 
Result so far: 14599.0
If we take 5589 away from 5897, we end up with 308.
Grab the next digit (6) from the dividend, add it to 308, then carry on: 3086 / 621

Advancing to step 8:
If we divide 3086 by 621, we get 4 and a remainder of 602.
Put 4 as the next digit of the answer. 
Result so far: 145994.0
If we take 2484 away from 3086, we end up with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 9:
If we divide 6020 by 621, we get 9 and a remainder of 431.
Record the quotient 9 as the next digit in the result. 
Result so far: 145994.9
The remainder is 431 after subtracting 5589 from 6020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 10:
The number 621 fits into 4310 6 times, leaving a remainder of 584.
The number 6 becomes the next digit in our result. 
Result so far: 145994.96
Subtracting 3726 from 4310 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 11:
621 goes into 5840 9 times with a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 145994.969
The remainder is 251 after subtracting 5589 from 5840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 12:
2510 divided by 621 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 145994.9694
If we subtract 2484 from 2510, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 13:
When dividing 260 by 621, we get 0 with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 145994.9694
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 14:
If we divide 2600 by 621, we get 4 and a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 145994.969404
The remainder is 116 after subtracting 2484 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 15:
If we divide 1160 by 621, we get 1 and a remainder of 539.
Put 1 as the next digit of the answer. 
Result so far: 145994.9694041
If we take 621 away from 1160, we end up with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

On to step 16:
When dividing 5390 by 621, we get 8 with a remainder of 422.
Record the quotient 8 as the next digit in the result. 
Result so far: 145994.96940418
If we subtract 4968 from 5390, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Our division results in 145994.96940418 with a remaining 4.22e-07.
